OK, let's crack this. We're given 308 and our task is to multiply it by 46. Essentially, we'll be adding 308 to itself 46 times.
Step 1: 0 + 308 = 308
Step 2: 308 + 308 = 616
Step 3: 616 + 308 = 924
Step 4: 924 + 308 = 1232
Step 5: 1232 + 308 = 1540
Step 6: 1540 + 308 = 1848
Step 7: 1848 + 308 = 2156
Step 8: 2156 + 308 = 2464
Step 9: 2464 + 308 = 2772
Step 10: 2772 + 308 = 3080
Step 11: 3080 + 308 = 3388
Step 12: 3388 + 308 = 3696
Step 13: 3696 + 308 = 4004
Step 14: 4004 + 308 = 4312
Step 15: 4312 + 308 = 4620
Step 16: 4620 + 308 = 4928
Step 17: 4928 + 308 = 5236
Step 18: 5236 + 308 = 5544
Step 19: 5544 + 308 = 5852
Step 20: 5852 + 308 = 6160
Step 21: 6160 + 308 = 6468
Step 22: 6468 + 308 = 6776
Step 23: 6776 + 308 = 7084
Step 24: 7084 + 308 = 7392
Step 25: 7392 + 308 = 7700
Step 26: 7700 + 308 = 8008
Step 27: 8008 + 308 = 8316
Step 28: 8316 + 308 = 8624
Step 29: 8624 + 308 = 8932
Step 30: 8932 + 308 = 9240
Step 31: 9240 + 308 = 9548
Step 32: 9548 + 308 = 9856
Step 33: 9856 + 308 = 10164
Step 34: 10164 + 308 = 10472
Step 35: 10472 + 308 = 10780
Step 36: 10780 + 308 = 11088
Step 37: 11088 + 308 = 11396
Step 38: 11396 + 308 = 11704
Step 39: 11704 + 308 = 12012
Step 40: 12012 + 308 = 12320
Step 41: 12320 + 308 = 12628
Step 42: 12628 + 308 = 12936
Step 43: 12936 + 308 = 13244
Step 44: 13244 + 308 = 13552
Step 45: 13552 + 308 = 13860
Step 46: 13860 + 308 = 14168

So, 308*46 = 14168
